  • Method for determining methanol content in crude oils
    Patent number: 9140674
    Abstract: A test method for the determination of methanol in crude oils to levels as low as 0.5 ppm is disclosed. The method includes extracting methanol into a water phase from a test sample of the crude oil forming a test sample extract. The method further includes extracting methanol into a water phase from a reference sample of the crude oil forming a reference sample extract, wherein the reference sample having a predetermined amount of methanol added thereto. The method further includes measuring the methanol content in the test sample extract and the methanol content in the reference sample extract. The method also includes determining the methanol content of the crude oil based upon the methanol content in the test sample extract and the methanol content in the reference sample extract.
